FIG. 1 is a diagram illustrating the structure of a service providing server for providing a game service that supports participation in a tournament for a game using a ticket according to one embodiment of the present invention and enables betting for members participating in the tournament.

Referring to FIG. 1, a service providing server (110) according to the present invention may include a game information storage unit (111), a ticket information storage unit (112), a wallet address storage unit (113), a confirmation unit (114), a reduction processing unit (115), an opening unit (116), and a processing unit (117).

The game information storage unit (111) stores information on the number of tickets required to participate in each tournament of a plurality of preset games.

For example, information may be stored in the game information storage unit (111) as shown in Table 1 below.

Multiple games Number of tickets required Game 1 2 pieces Game 2 1 piece Game 3 5 pieces Game 4 7 pieces ... ...

The ticket information storage unit (112) stores information on the number of tickets held by each of the multiple members registered for the game service.

For example, information may be stored in the ticket information storage unit (112) as shown in Table 2 below.

Multiple members Number of tickets held Member 1 10 pieces Member 2 30 pieces Member 3 0 items Member 4 5 pieces ... ...

The wallet address storage unit (113) stores information about wallet addresses for accumulating cryptocurrency held by each of the above multiple members.

For example, information may be stored in the wallet address storage unit (113) as shown in Table 3 below.

Multiple members Wallet address Member 1 Address 1 Member 2 Address 2 Member 3 Address 3 Member 4 Address 4 ... ...

In this situation, the operator of the service providing server (110) of the present invention may hold a tournament competition for each of the plurality of games in order to provide the game service, and at this time, the operator may open a tournament session for each of the plurality of games online in order to allow members to participate in the tournament competition for each of the plurality of games online through electronic terminals they possess.

In this regard, FIG. 2 is a drawing showing an example of a screen in which a tournament session for each of the plurality of games is opened, which can be viewed through the electronic terminal when a specific member accesses the service provision server (110) through his or her electronic terminal. Here, when reference numeral 211 of FIG. 2 is a screen in which a tournament session for the first game, which is one of the plurality of games, is opened, the tournament session means a session opened so that members who access the tournament session through their electronic terminals can play the first game together online. That is, multiple members can play the first game together online by accessing the tournament session through their electronic terminals.

Accordingly, when one of the plurality of members, the first member, accesses the service provision server (110) through his/her first electronic terminal (10), the first member can view a waiting room screen having a UI as shown in FIG. 2 through the first electronic terminal (10).

At this time, when the first member clicks on the tournament session for the first game indicated by reference numeral 211 through the first electronic terminal (10), the first electronic terminal (10) can transmit a connection request command to the tournament session to the service providing server (110) of the present invention.

At this time, when a connection request command for a tournament session opened for the first game is received from the first electronic terminal (10), the verification unit (114) authenticates the first member, then refers to the game information storage unit (111) to confirm the first required number of tickets required to participate in the tournament of the first game, and refers to the ticket information storage unit (112) to confirm the number of tickets held by the first member.

If the reduction processing unit (115) confirms that the number of tickets held by the first member is greater than or equal to the first required number, it allows access to the tournament session of the first electronic terminal (10) and then reduces the number of tickets held by the first member stored in the ticket information storage unit (112) by the first required number.

In this regard, assuming that information is stored in the game information storage unit (111) as shown in Table 1, and that information is stored in the ticket information storage unit (112) as shown in Table 2, and that the first game is 'Game 2' and the first member is 'Member 4', since the number of tickets held by 'Member 4', which is '5', is greater than or equal to the first required number of '1' for participating in the tournament for 'Game 2', the reduction processing unit (115) can reduce the number of tickets held by 'Member 4' stored in the ticket information storage unit (112) by '1' and change it to '4' after allowing access to the tournament session for 'Game 2' of the first electronic terminal (10).

In this way, after access to the tournament session of the first electronic terminal (10) is permitted, if the first member is matched with the second member who has accessed the tournament session and performs a match for the first game, the opening unit (116) opens a betting session to enable betting on the member predicted to win between the first member and the second member.

The processing unit (117) receives a betting request command for either the first member or the second member from the electronic terminals of the plurality of betting participating members who are connected to the betting session among the plurality of members, and if it is determined that the first member has won as a result of the match for the first game, the processing unit (117) verifies the wallet addresses of each of the first betting members who have bet on the first member among the plurality of betting participating members by referring to the wallet address storage unit (113), and then transfers a cryptocurrency in the amount of the preset dividend payment amount to the wallet addresses of each of the first betting members, thereby completing the compensation processing for the first betting members; and if it is determined that the second member has won, the processing unit (113) verifies the wallet addresses of each of the second betting members who have bet on the second member among the plurality of betting participating members by referring to the wallet address storage unit (113), and then transfers a cryptocurrency in the amount of the dividend payment amount to the wallet addresses of each of the second betting members, thereby completing the compensation processing for the second betting members.

In relation to this, let us assume that information is stored in the wallet address storage unit (113) as shown in Table 3, that the first member is 'Member 4', the second member is 'Member 2', and that the first game is 'Game 2', and that after access to the tournament session for 'Game 2' of the first electronic terminal (10) is permitted by the reduction processing unit (115), 'Member 4' is matched with 'Member 2' who accessed the tournament session for 'Game 2' and a match for 'Game 2' is performed.

Then, the opening section (116) can open a betting session to allow betting on which member is predicted to win between 'Member 4' and 'Member 2'.

At this time, if the multiple betting participating members who have connected to the betting session among the multiple members are called 'Member 5, Member 6, Member 7, Member 8, and Member 9', a betting request command for 'Member 4' can be received by the service providing server (110) from the electronic terminals of 'Member 5, Member 8, and Member 9', and a betting request command for 'Member 2' can be received by the service providing server (110) from the electronic terminals of 'Member 6, Member 7'.

If, as a result of the match for 'Game 2' where 'Member 4' and 'Member 2' are matched, 'Member 4' is determined to have won, the processing unit (117) can, by referring to the wallet address storage unit (113), check the wallet addresses of 'Member 5', 'Member 8', and 'Member 9' who bet on 'Member 4' as 'Address 5', 'Address 8', and 'Address 9'.

At this time, if the cryptocurrency equivalent to the preset dividend payment amount is called '1 coin', the processing unit (117) can complete the compensation processing for 'members 5, 8, and 9' who succeeded in betting in the match for 'game 2' by transferring the cryptocurrency equivalent to '1 coin' to 'address 5, address 8, and address 9'.

According to one embodiment of the present invention, the service providing server (110) may further include a transaction generation unit (118) and a registration request unit (119).

When the processing unit (117) completes the transfer of cryptocurrency equivalent to the dividend payment amount for the first game, the transaction generation unit (118) generates a transaction including information on the win/loss result for the first game, information on betting members who received the dividend payment amount, and information on the dividend payment amount received by each betting member.

When the above transaction is generated, the registration request unit (119) randomly selects a first node device, which is one of a plurality of node devices (101, 102, 103, 104, 105, 106) constituting the blockchain network (100), transmits the transaction to the first node device, and transmits a registration request for the transaction to the blockchain network (100).

In relation to this, as in the above-described example, let us assume that the first game is called 'Game 2', and since it is determined that 'Member 4' won the match against 'Game 2', the processing unit (117) has completed the transfer of cryptocurrency equivalent to '1 coin' as the dividend payment amount for 'Member 5, Member 8, and Member 9' who bet on 'Member 4'.

Then, the transaction generation unit (118) can generate a transaction that includes information on the win/loss result for 'Game 2', information on 'Member 5, Member 8, and Member 9' who received the above dividend payment amount, and information on the cryptocurrency equivalent to '1 coin' paid to each betting member.

Then, the registration request unit (119) can randomly select one node device (101) among the plurality of node devices (101, 102, 103, 104, 105, 106) constituting the blockchain network (100), and the registration request unit (119) can transmit a registration request for the transaction to the blockchain network (100) while transmitting the transaction to the node device (101).

At this time, when the transaction and the registration request are received from the service providing server (110) to the first node device, the first node device creates a first block including the transaction based on a previous block linked to the blockchain data stored in the memory of the first node device, links the first block to the blockchain data in a chain, thereby completing storage of the first block, and then transmits the first block to the remaining node devices excluding the first node device among the plurality of node devices (101, 102, 103, 104, 105, 106) through the blockchain network (100).

For example, as in the example described above, when the registration request unit (119) transmits the transaction to the node device (101) and transmits a registration request for the transaction to the blockchain network (100), and the transaction and the registration request are received by the node device (101) from the service providing server (110), the node device (101) can generate a first block including the transaction based on a previous block linked in a chain to the blockchain data stored in the memory of the node device (101).

Then, the node device (101) can propagate the first block to the remaining node devices (102, 103, 104, 105, 106) through the blockchain network (100) after completing the storage of the first block by chaining the first block to the blockchain data. Then, the remaining node devices (102, 103, 104, 105, 106) can share the transaction by chaining the first block to the blockchain data based on the previous block chained to the blockchain data stored in each node device.

According to one embodiment of the present invention, the service providing server (110) may further include a compensation information storage unit (120), a compensation confirmation unit (121), and a compensation processing unit (122).

The reward information storage unit (120) stores information on the amount of cryptocurrency to be paid as a reward when winning a tournament for each of the above-mentioned multiple games.

For example, information may be stored in the compensation information storage unit (120) as shown in Table 4 below.

Multiple games Cryptocurrency payout upon winning Game 1 5 coins Game 2 2 coins Game 3 13 coins Game 4 20 coins ... ...

When the first electronic terminal (10) accesses the tournament session, and the first member wins the tournament for the first game, and an event occurs through the tournament session indicating that the first member is the winner due to the first member winning the tournament for the first game, the reward verification unit (121) verifies the first payment amount, which is the amount of cryptocurrency to be paid as a reward when winning the tournament for the first game, by referring to the reward information storage unit (120), and verifies the wallet address of the first member by referring to the wallet address storage unit (113).

The compensation processing unit (122) completes the compensation processing for the first member by transferring cryptocurrency equivalent to the first payment amount to the wallet address of the first member.

In relation to this, as in the example described above, let us assume that information such as Table 3 is stored in the wallet address storage unit (113). In addition, let us assume that the first member is 'Member 4', the first game is 'Game 2', and 'Member 4' has completed participation in the tournament for 'Game 2' as the first electronic terminal (10) accesses the tournament session opened for 'Game 2'.

If 'Member 4' wins the tournament for 'Game 2', the service providing server (110) can generate an event indicating that 'Member 4' is the winner through the tournament session opened for 'Game 2'. In this way, if an event indicating that 'Member 4' is the winner occurs through the tournament session for 'Game 2', the reward confirmation unit (121) can refer to the reward information storage unit (120) to confirm the amount of cryptocurrency to be paid as a reward when winning the tournament for 'Game 2' as '2 coins', and can refer to the wallet address storage unit (113) to confirm the wallet address of 'Member 4' as 'Address 4'.

Then, the compensation processing unit (122) can complete the compensation processing for ‘Member 4’ by transferring cryptocurrency equivalent to ‘2 coins’ to ‘Address 4’, which is the wallet address of ‘Member 4’.

Through this, members will be able to receive rewards in cryptocurrency when they win a tournament for a game they participated in, and these rewards will encourage them to participate in tournaments for the game more actively.

According to one embodiment of the present invention, the service providing server (110) may further include a price information storage unit (123), a payment processing unit (124), and an augmentation processing unit (125).

The price information storage unit (123) stores the purchase price information for tickets for participating in the tournament.

For example, the price information storage unit (123) may store purchase price information such as '5,000 won per ticket' as ticket purchase price information.

When a purchase request command requesting to purchase tickets in the first purchase quantity is received from a third electronic terminal of a third member, who is one of the plurality of members, the payment processing unit (124) requests transmission of payment method information to the third electronic terminal, and when the first payment method information is received from the third electronic terminal, the unit calculates a price corresponding to the first purchase quantity based on the purchase price information, and then performs payment processing for the calculated price based on the first payment method information.

For example, let's assume that the third member is called 'Member 3' and the ticket purchase price information is set to '5,000 won per ticket'.

At this time, if a purchase request command requesting the purchase of '5' tickets from the third electronic terminal of 'Member 3' is received by the service providing server (110), the payment processing unit (124) requests the transmission of payment method information to the third electronic terminal, and if credit card information is received by the service providing server (110) from the third electronic terminal in response thereto, the payment processing unit (124) can calculate the price of the purchase quantity of '5' tickets as '25,000 won' based on the purchase price information, and then process the payment for '25,000 won' based on the credit card information.

When the payment processing is completed, the augmentation processing unit (125) increases the number of tickets held by the third member stored in the ticket information storage unit (112) by the first purchase quantity.

In relation to this, as in the example described above, if information such as Table 2 is stored in the ticket information storage unit (112) and payment processing for '25,000 won' is completed by the payment processing unit (124), the increase processing unit (125) can increase the number of tickets held by 'member 3' stored in the ticket information storage unit (112) by '5' and change it to '5'.

According to one embodiment of the present invention, when a connection request command for a tournament session opened for the first game is received from the first electronic terminal (10) of the first member, the service providing server (110) may further include a configuration for performing authentication on the first member and, only when it is confirmed that the first member is an authenticated member, proceeding with a process for determining whether to allow the first electronic terminal (10) to connect to the tournament session based on a ticket held by the first member.

To this end, the verification unit (114) may include an email storage unit (126), a public key storage unit (127), an authentication event generation unit (128), an authentication information generation unit (129), a calculation unit (130), an authentication request unit (131), and an authentication processing unit (132).

The email storage unit (126) stores information about preset email addresses for each of the plurality of members.

In relation to this, information may be stored in the email storage unit (126) as shown in Table 5 below.

Multiple members Email address Member 1 Email address 1 Member 2 Email address 2 Member 3 Email address 3 Member 4 Email address 4 ... ...

In the public key storage unit (127), a public key corresponding to a private key issued in advance for each of the plurality of members (the private key of each of the plurality of members is stored in each member's electronic terminal) is stored.

In relation to this, information may be stored in the public key storage unit (127) as shown in Table 6 below.

Multiple members Public key Member 1 Public key 1 Member 2 Public key 2 Member 3 Public key 3 Member 4 Public key 4 ... ...

When a connection request command to the tournament session is received from the first electronic terminal (10), the authentication event generation unit (128) generates an authentication event to proceed with authentication of the first member.

When the above authentication event occurs, the authentication information generation unit (129) randomly generates a first authentication number of n digits (n is a natural number greater than or equal to 2), randomly generates an authentication value composed of a natural number having a size of 9 or less, and then performs a modulo operation with the authentication value as a divisor for each digit of the first authentication number, thereby generating a second authentication number of n digits.

For example, if n is '3', the authentication information generation unit (129) randomly generates a three-digit first authentication number, such as '642', and randomly generates the authentication value, such as '5', and then performs a modulo operation with the authentication value, '5', as a divisor for the digits '6', '4', and '2' that constitute the first authentication number, thereby generating a three-digit second authentication number, such as '142'.

The calculation unit (130) generates a column vector having as components the numbers of each digit constituting the first authentication number and a row vector having as components the numbers of each digit constituting the second authentication number, and calculates the matrix product between the column vector and the row vector to generate an operation matrix of size n x n, and then calculates the Frobenius norm of the operation matrix.

Here, the Frobenius norm refers to the L2-Norm, which represents the size of the matrix.

In relation to this, as in the example described above, if the first authentication number is generated as '642' and the second authentication number is generated as '142' through the authentication information generation unit (129), the calculation unit (130) generates a column vector having the numbers of each digit constituting the first authentication number '642' as components. ' is generated as '[1 4 2]', and a row vector having the numbers of each digit constituting the second authentication number '142' as components is generated as '[1 4 2]', and then a matrix product between the column vector and the row vector is calculated, thereby generating a 3 x 3 sized operation matrix. ' can be generated, and the Frobenius norm of the above operation matrix can be computed.

The authentication request unit (131) verifies the first email address of the first member by referring to the email storage unit (126), sends an authentication email including the first authentication number to the first email address as the recipient, and then transmits the authentication value to the first electronic terminal (10) and requests an electronic signature based on the first authentication number and the authentication value.

For example, as in the above-described example, if the first authentication number and the authentication value are '642' and '5', respectively, and the first member is 'Member 4', the authentication request unit (131) can refer to the email storage unit (126) as in Table 5, check the 'email address 4' for 'Member 4', and send an authentication email including the first authentication number '642' to the 'email address 4' as the recipient. Then, the authentication request unit (131) can transmit the authentication value '5' to the first electronic terminal (10) and request an electronic signature based on the first authentication number and the authentication value.

At this time, according to one embodiment of the present invention, when the electronic signature request is received from the service providing server (110) together with the authentication value, the first electronic terminal (10) may display a message requesting the first member to input the first authentication number included in the authentication email received in the account according to the first email address into the first electronic terminal (10).

At this time, when the first member inputs the first authentication number included in the authentication email received in the account according to the first email address in response to the message into the first electronic terminal (10), the first electronic terminal (10) generates the second authentication number of n digits by performing a modulo operation with the authentication value as a divisor on each digit constituting the first authentication number, and then generates a column vector having each digit constituting the first authentication number as a component and a row vector having each digit constituting the second authentication number as a component, and then generates the operation matrix of size n x n by calculating the matrix product between the column vector and the row vector, and then generates a first electronic signature value by signing the Frobenius norm of the operation matrix with the first private key for the first member stored in the first electronic terminal (10), and then transmits the result to the service providing server (110) of the present invention.

In relation to this, as in the above-described example, if the first authentication number and the authentication value are respectively '642' and '5', and the first member is 'Member 4', when the electronic signature request is received from the service providing server (110) together with the authentication value '5', the first electronic terminal (10) may display a message requesting 'Member 4' to input the first authentication number included in the authentication email received in the account according to 'Email address 4' into the first electronic terminal (10).

Then, 'Member 4' can log in to the account according to 'Email address 4', check the authentication email, and enter the first authentication number '642' included in the authentication email into the first electronic terminal (10).

In this way, when 'member 4' enters the first authentication number '642' included in the authentication email into the first electronic terminal (10), the first electronic terminal (10) can generate the three-digit second authentication number '142' by performing a modulo operation with the authentication value '5' as a divisor for the numbers '6', '4', and '2' that constitute the first authentication number.

Then, the first electronic terminal (10) generates a column vector having each digit of the first authentication number, '642', as a component. ' is generated as '[1 4 2]', and a row vector having the numbers of each digit constituting the second authentication number '142' as components is generated as '[1 4 2]', and then a matrix product between the column vector and the row vector is calculated, thereby generating a 3 x 3 sized operation matrix. ' can be generated. Then, the first electronic terminal (10) calculates the Frobenius norm of the operation matrix, and then performs an electronic signature on the Frobenius norm based on 'private key 4', which is a private key for 'member 4' pre-stored on the first electronic terminal (10), thereby generating a first electronic signature value and transmitting it to the service providing server (110) of the present invention.

The authentication processing unit (132) generates, from the first electronic terminal (10), in response to the electronic signature request, a first electronic signature value (the first electronic signature value is the authentication value received by the first electronic terminal (10), and when the first member enters the first authentication number included in the authentication email received in the account according to the first email address into the first electronic terminal (10), the first electronic terminal (10) performs a modulo operation with the authentication value as a divisor on each digit of the number constituting the first authentication number, thereby generating the second authentication number of n digits, and then generates a column vector having the digits of each digit of the first authentication number as components and a row vector having the digits of each digit of the second authentication number as components, and then generates the operation matrix of n x n size by calculating the matrix product between the column vector and the row vector, and then generates the Frobenius norm of the operation matrix as the first for the first member stored in the first electronic terminal (10). When the generated value (by signing with a private key) is received, the first public key for the first member is extracted from the public key storage unit (127), and the value obtained by decrypting the first electronic signature value based on the first public key is compared with the Frobenius norm of the operation matrix. If it is confirmed that the two values match each other, the authentication process for the first member is completed.

In relation to this, as in the example described above, if the first member is 'Member 4', when the authentication processing unit (132) receives the first electronic signature value from the first electronic terminal (10), it extracts 'public key 4', which is a public key for 'Member 4', from the public key storage unit (127) as shown in Table 6, and then can decrypt the first electronic signature value based on 'public key 4'.

Thereafter, the authentication processing unit (132) compares the decrypted value for the first electronic signature value with the Frobenius norm of the operation matrix, and if it is confirmed that the two values match each other, the authentication for 'member 4' can be completed.
